Unfortunately, labour turnover has become a common phenomenon globally among knowledge<br />

workers (Costello, 2001; Martin 2003). Martin (2003) conducted a study on tenure and labour<br />

turnover of knowledge employees in Australia, Europe, Japan and the United States between<br />

1980 and 2000 and found that employees in Japan are more likely to stay longer with one<br />

employer than is the case in Europe and Australia. Findings in Europe showed that labour<br />

turnover was low in France, Germany, the Netherlands and Norway while higher in the rest of the<br />

continent for all categories of employees. In the United States the average professional holds 18<br />

different jobs before they retire. This suggests that professionals stay for less than three years in a<br />

job throughout their career.<br />

Martin (2003) defines labour turnover as a flow concept measured over a period, usually a year.<br />

This definition includes all leavers during the period, irrespective of whether they left voluntarily<br />

or due to redundancy or dismissals or retirement. Morrell, Loan-Clarke and Wilkinson (2001:6)<br />

define labour turnover as a “voluntary cessation of membership of an organisation by an<br />

employee of that organisation”. It is important to understand labour turnover within the context<br />

of employees leaving voluntarily because they control the decision to leave, hence the high<br />

interest by organisations to understand and curtail this phenomenon. The term is commonly used<br />

to describe the number of employees leaving the organisation voluntarily. Generally,<br />

organisations need to pass the test of retaining the majority of employees that joined in<br />

permanent positions in a given year of reporting. In discussing labour turnover, this section will<br />

focus on the act of leaving and factors that influence employees’ decisions to leave the<br />

organisation voluntarily.<br />

2.3.2 Factors that cause labour turnover among knowledge workers<br />

Given that some employees will leave their employer at some point in their career, it usually<br />

takes a while between the time they decide to leave and the actual time of departure (Drury,<br />

2003; Kinnear, 1999; Kaye and Jordan-Evans, 2002). In addition to the time lag, there are various<br />

reasons why employees decided to leave (Kaye and Jordan-Evans, 2002; Stewart, 1997). It is<br />

generally accepted that either ‘push’ or ‘pull’ factors induce employees to leave their employer<br />

(Branham, 2005; Kaye and Jordan-Evans, 2002). Push factors refer to those factors inherent in<br />
